Wang M, Hua Y, Bai Y. A review of the application of exercise intervention on improving cognition in patients with Alzheimer's disease: mechanisms and clinical studies. Rev Neurosci 2024; 0:revneuro-2024-0046. [PMID: 39029521 DOI: 10.1515/revneuro-2024-0046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2024] [Accepted: 07/08/2024] [Indexed: 07/21/2024]
Abstract
Alzheimer's disease (AD) is the most common form of dementia, leading to sustained cognitive decline. An increasing number of studies suggest that exercise is an effective strategy to promote the improvement of cognition in AD. Mechanisms of the benefits of exercise intervention on cognitive function may include modulation of vascular factors by affecting cardiovascular risk factors, regulating cardiorespiratory health, and enhancing cerebral blood flow. Exercise also promotes neurogenesis by stimulating neurotrophic factors, affecting neuroplasticity in the brain. Additionally, regular exercise improves the neuropathological characteristics of AD by improving mitochondrial function, and the brain redox status. More and more attention has been paid to the effect of Aβ and tau pathology as well as sleep disorders on cognitive function in persons diagnosed with AD. Besides, there are various forms of exercise intervention in cognitive improvement in patients with AD, including aerobic exercise, resistance exercise, and multi-component exercise. Consequently, the purpose of this review is to summarize the findings of the mechanisms of exercise intervention on cognitive function in patients with AD, and also discuss the application of different exercise interventions in cognitive impairment in AD to provide a theoretical basis and reference for the selection of exercise intervention in cognitive rehabilitation in AD.

Comparing the efficacy of traditional Chinese exercises and general aerobic exercises in university students with sleep disorders: A systematic review and meta-analysis. Medicine (Baltimore) 2024; 103:e38521. [PMID: 38847687 PMCID: PMC11155542 DOI: 10.1097/md.0000000000038521] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Accepted: 05/17/2024] [Indexed: 06/10/2024] Open
Abstract
BACKGROUND The objective of this study was to compare the impact of traditional Chinese exercise (TCEs) and general aerobic exercise (GAEs) on the sleep quality of university students and to determine which exercise is more effective in improving sleep quality in this specific population. METHODS We utilized Review Manager 5.3 to analyze data from 21 randomized controlled trials (RCTs), which included a total of 1252 participants. Effect sizes of TCEs and GAEs were compared using a random-effects model. Subgroup analyses were conducted on 3 modulating variables: times per session, frequency per week, and period. RESULTS A Meta-analysis of 14 RCTs showed that both TCEs (standard mean difference [SMD] = -0.89, 95% CI: -1.18 to -0.61; P < .00001) and GAEs (SMD = -1.53, 95% CI: -2.10 to -0.97; P < .00001) can significantly improve the sleep of university students, with a significant difference between TCEs and GAEs (P = .05). Both GAEs and TCEs had positive effects on various aspects of sleep quality, including subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleep medication, and daytime dysfunction. A subgroup analysis of aerobic exercise showed that the effect size was larger in the 40 to 60 minutes group compared to the 60 to 90 minutes group (SMD = -1.89; 95% CI: -2.19 to -1.59; P < .00001). Furthermore, the effect size was larger in the 3 to 5 times per week group compared to the 2 times per week group (SMD = -1.56; 95% CI: -2.33 to -0.80; P < .0001). The effect size was also found to be larger in a period of 2 to 4 weeks compared to 6 to 18 weeks (SMD = -1.85; 95% CI: -2.17 to -1.54; P < .00001). CONCLUSION GAEs is more effective than TCEs in improving the sleep quality of university students. An optimal aerobic exercise regimen for enhancing sleep quality among university students involves engaging in sessions lasting 40~60 minutes, 3~5 times per week, over a duration of 4 weeks.

Abstract
PURPOSE While clinical research has shown that Tai Chi exercise may improve the sleep quality of older adults, there is a lack of robust evidence-based verification. Therefore, this study conducted a systematic review of published research on the effect of Tai Chi exercise on the sleep quality of community-dwelling older adults, aiming to provide solid evidence-based medicine to enhance their sleep quality. METHODS A systematic search was conducted on PubMed, Embase, Cochrane Library, Web of Science, CNKI, WanFang, VIP, and SinoMed databases from their inception to December 9, 2022. The Cochrane risk of bias assessment tool 2.0 was used to assess the risk of bias in the included studies. RESULTS This systematic review included 12 original articles, involving a total of 1,058 community-dwelling older adults, with 553 in the Tai Chi group and 505 in the control group. The meta-analysis results revealed a significant improvement in the sleep quality of community-dwelling older adults who practiced Tai Chi compared to the control group [WMD = - 1.96 (95% CI: - 3.02 to - 0.90, z = 3.62, P < 0.001)]. Subgroup analysis showed that Tai Chi had significantly beneficial effects regardless of age, country/region, intervention time, and Tai Chi type. CONCLUSIONS Tai Chi exercise can serve as an effective non-medication approach for addressing sleep problems in this demographic. Among the various types of Tai Chi exercises, the 24-form Tai Chi exercise emerges as a preferred option. Moreover, Tai Chi exercise proves to be an excellent choice for older people in their later years, promoting their overall well-being and health.

Abstract
OBJECTIVES This study aimed to investigate the association between recovery from work and insomnia and the role of objectively measured leisure-time physical activity and occupational physical activity in this association. DESIGN Cross-sectional. SETTING AND PARTICIPANTS Study with female early childhood education and care professionals (N=224) in Finland was conducted between April 2017 and September 2018. METHODS Recovery from work was measured with the Need for Recovery scale and insomnia with the Jenkins Sleep Scale. Physical activity was measured with an accelerometer for 7 days and analysed to represent leisure-time physical activity and occupational physical activity (min/day). RESULTS Both Jenkins Sleep Scale and occupational physical activity significantly predicted Need for Recovery (β=0.29; 95% CI 0.17 to 0.42 and β=0.14; 95% CI 0.01 to 0.27, respectively). A low relationship was observed between the Need for Recovery and Jenkins Sleep Scale (r=0.32, 95% Cl 0.19 to 0.44). After categorising participants into four groups based on median splits of occupational and leisure-time physical activity, relationships between the Need for Recovery and Jenkins Sleep Scale were low to moderate in the high occupational physical activity and leisure time physical activity group (r=0.38, 95% Cl 0.14 to 0.61), and in the high occupational physical activity and low leisure-time physical activity group (r=0.40, 95% Cl 0.18 to 0.63). CONCLUSION Both insomnia and physical activity at work seem to be relevant in recovery from work. To enhance recovery, especially those involved in high physical activity at work, should seek methods to improve recovery, by incorporating activities that promote recuperation both during their workday and in their leisure time. Further research on the relevance of physical activity in recovery with longitudinal setting is warranted. TRIAL REGISTRATION NUMBER NCT03854877.

Abstract
Background Obstructive sleep apnea (OSA) is a common disorder that affects approximately 1 billion people worldwide. Advanced age is a significant risk factor. Various treatment options have been explored to reduce the severity of OSA symptoms and physical exercise has emerged as a potential alternative therapy. Therefore, this study aims to investigate the effects of a combined exercise program with sleep education on sleep quality and on the severity of OSA in older adults. Methods This is a randomized clinical trial with two parallel groups that will involve individuals of both genders aged between 60 and 79 years who have an apnea-hypopnea index (AHI) of more than 15 events per hour and who have not received or are currently undergoing treatment for OSA. Older adults who have engaged in regular exercise in the last six months and individuals with contraindications to exercise will be excluded. The study will assess outcomes related to OSA, including AHI, oxygen desaturation index, minimum and mean oxyhemoglobin saturation, sleep efficiency, sleep latency, and the type of respiratory events. Additionally, sleep quality-related outcomes, daytime sleepiness, physical activity, physical fitness, aerobic capacity, cognitive status, anthropometric measures, and health-related quality of life will be analyzed. Participants will be randomized to two groups: a combined exercise group (involving both resistance and aerobic training) with sleep education, and a control group that will receive only educational recommendations for managing OSA. The intervention will last 12 weeks and will consist of three sessions per week, totaling 36 exercise sessions. Sample size calculation indicates a minimum number of 36 participants. Discussion If the hypothesis is confirmed, this clinical trial will indicate an effective non-pharmacological intervention for treating OSA in older adults. This intervention could be used as an adjunct to existing approaches designed to improve OSA management. Clinical trail registration Brazil Clinical Trials Registry (ReBEC), identifier RBR-9hk6pgz.

Abstract
Physical activity (PA) has pluripotential beneficial effects on body functions. These benefits include reduction in the incidence of cardiovascular disease (CVD), coronary heart disease (CHD), hypertension, type 2 diabetes mellitus (T2DM), and death. In addition to these effects, PA exerts significant beneficial effects on sleep onset, duration and quality, which add to its beneficial effects. In contrast, lack of sleep has been associated with increased incidence of CVD complications and death. In this regard, PA serves as a non-pharmacologic means for sleep improvement especially in older people, who frequently have difficulties in falling asleep. Regarding the timing of exercise and its effect on sleep, there has been no difference between morning and evening exercise on the onset and quality of sleep. With respect the beneficial cardiovascular effects of PA on sleep, there has been a debate among several investigators with some reporting significant beneficial effects of PA, and others reporting not significant beneficial effects. In order to get a better perspective on the effects of PA on quality of sleep, and its cardiovascular beneficial effects, a Medline search of the English literature was conducted between 2017 and 2023 using the terms exercise, sleep, cardiovascular disease, death and 36 pertinent papers were selected (Figure 1). The findings from these papers together with collateral literature will be discussed in this review.

Abstract
Most older adults wish to maintain independence in their familiar communities. However, many experience pain and pain-related disabilities which reduce their health-related quality of life (HRQOL), leading to increased hospitalizations and mortality. This study aimed to determine the impact of physical, mental, and cognitive factors, particularly central sensitization-related symptoms (CSS), on the HRQOL of community-dwelling older adults. A total of 206 participants were included in the analysis, which measured HRQOL, basic attributes, physical functions and body pain, mental factors, cognitive factors, and CSS severity using validated tools. A correlation analysis was used to examine the association between HRQOL and each measure. Furthermore, multiple regression analysis (forced entry method) was performed to identify the factors influencing the HRQOL. The study found that pain intensity and CSS severity significantly influenced the HRQOL among community-dwelling older adults. The higher the pain intensity and CSS severity, the lower their HRQOL. The participants had mild pain and CSS, demonstrating the need to monitor, address, and treat even non-severe issues in community-dwelling older adults. This association, revealed for the first time in this study, suggests that approaches to reduce pain and CSS are important for maintaining and improving the HRQOL of community-dwelling older adults.

Abstract
The objective of this study is to investigate the impact of exercise habits on enhancing the sleep quality of older adults. The Pittsburgh Sleep Quality Scale and other questionnaires were utilized to assess the sleep quality of older adults aged 60 years and above in the H district. The sampling method employed was stratified random sampling. To analyze the influencing factors of sleep quality, the average treatment effect was estimated, the robustness of the results was assessed and statistical methods such as Logit regression and propensity score matching were employed. The study revealed that exercise habits strongly correlated with improved sleep quality in the older adult (p < 0.05), with the average total sleep quality score being 6.22 (±3.53). It was observed that older adults who engaged in exercise habits experienced a significant 12.66% increase in the likelihood of achieving good sleep. This investigation highlights the positive association between exercise habits and enhanced sleep quality among older adults. Additionally, age, physical pain and self-rated health statuses were identified as significant factors influencing sleep quality in this population. To enhance the sleep quality of older adults, this article recommends promoting relevant exercise habits, thus contributing to their overall well-being and quality of life.

Effects of a 24-Week Low-Cost Multicomponent Exercise Program on Health-Related Functional Fitness in the Community-Dwelling Aged and Older Adults. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59020371. [PMID: 36837572 PMCID: PMC9961982 DOI: 10.3390/medicina59020371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 02/09/2023] [Accepted: 02/13/2023] [Indexed: 02/17/2023]
Abstract
Background and Objectives: This study aimed to examine the effects of a low-cost multicomponent exercise program on health-related functional fitness in the community-dwelling aged and older adults. As a second objective, this study compared the exercise program between aged adults (<65 years) and those considered elderly (≥65 years). Materials and Methods: Forty-eight participants were included in the exercise program, and their mean age was 64.73 years (±5.93 years). The Senior Fitness Tests were performed by each participant. A dynamometer was used to assess hand grip strength, and body composition was assessed considering the body mass index. Paired-sample t test was used to compare data at baseline and after the exercise program, considering the total sample. Afterwards, a 2 × 2 analysis of variance was used to examine differences within and between groups. Results: Statistically significant improvements in the chair stand (t = -14.06; p < 0.001; d = 0.42), arm curl (t = -12.10; p < 0.001; d = 0.58), 2 min step test (t = -9.41; p < 0.001; d = 0.24), timed up and go test (t = 5.60; p < 0.001; d = 0.19), and hand grip strength (t = -3.33; p < 0.001; d = 0.15) were observed. There were also significant differences in the back scratch (t = -6.68; p < 0.001; d = 0.18) and chair sit and reach test (t = 5.04; p < 0.001; d = 0.05), as well as body mass index (p < 0.05). No significant differences were found between groups (p > 0.05). Conclusion: This study provides evidence that a 24-week low-cost community-based exercise program can improve functional fitness in aged and in older adults. The exercise program supplied the necessary data to construct further randomized controlled trials that can be performed in the community in an environmentally sustainable fashion and applied, not only to the elderly, but also to those transitioning to this age group.

Abstract
ObjectivesThis study aimed to investigate the effects of Ramadan diurnal intermittent fasting (RDIF) on cognitive performance, sleep quality, daytime sleepiness, and insomnia in physically active and sedentary elderly individuals.MethodsA total of 58 participants (62.93 ± 3.99 years) were assigned to one of the following two groups: a sedentary group (control group) who observed Ramadan (n = 32) and a physically active group (n = 26) who continued to train while observing Ramadan. Participants were assessed 2 weeks before Ramadan and during the fourth week of Ramadan. On each occasion, participants completed a digital assessment of their cognitive performance and responded to the Pittsburgh sleep quality index (PSQI), the insomnia severity index (ISI) and the Epworth sleepiness scale (ESS) questionnaires to assess sleep parameters.ResultsCompared to before Ramadan, performance in executive function (p = 0.035), attention (p = 0.005), inhibition (p = 0.02), associative memory (p = 0.041), and recognition memory (p = 0.025) increased significantly during Ramadan in the physically active group. For the sedentary group, associative learning performance decreased (p = 0.041), whilst performances in the remaining domains remained unchanged during Ramadan. Global PSQI, ISI, and ESS scores indicated both groups suffered from poor sleep quality and excessive daytime sleepiness, with significantly higher negative effects of RDIF observed in the sedentary group.ConclusionOlder adults who continue to train at least three times per week during Ramadan may improve their cognitive performance, despite the impairment of sleep quality. Future studies in older adults during Ramadan including objective measures of sleep (e.g., polysomnography, actigraphy) and brain function (e.g., functional magnetic resonance imaging) are warranted.

Abstract
Exercise interventions have shown significant improvements in the older adult population regarding functional and cognitive capacity. However, much research has applied exercise protocols that are expensive both for research and participation. Thus, high investments that are made are currently not ecologically efficient. The aim of the study was to determine whether the impact of a 20-week multicomponent exercise intervention using low-cost material could improve physical fitness in community-dwelling older adults. We tested the feasibility of this three times per week exercise protocol using an inclusive approach. Eligibility criteria included age ≥65 years, the ability to stand and walk with or without assistive devices, being physically inactive; medical clearance, and living in the community. Outcomes were muscle resistance measured using the chair-stand test for lower limbs, cardiorespiratory capacity measured using the 6-min walk test, and agility and balance using the Timed-up and Go test. Flexibility was measured using the chair sit and reach for lower limbs and the back scratch for upper limbs using the dominant leg and arm, respectively. Hand grip strength was measured using a dynamometer. Thirty participants (n = 30) were recruited and included in the intention-to-treat analysis. The mean age of participants was 70 years (±3.62 years), 100% were Caucasians, and 50% were female. There was a significant trend toward a clinically important improvement in the chair-stand (t = -5.23; p < 0.001; d = 0.36), arm curl (t = -5.21; p < 0.001; d = 0.74), 6-min walk test (t = -4.69; p = <0.001; d = 0.77), timed-up and go test (t = 8.788; p < 0.001; d = 1.18), and hand grip strength (t = 2.846; p = 0.009; d = 0.23). There were also differences in the back scratch (t = 2.243; p = 0.035; d = 0.29) and chair sit and reach test (t = -3.380; p < 0.001; d = 0.15). This pilot study has provided preliminary evidence that a 20-week community-based low-cost exercise program may be effective in improving overall functional fitness in older people. The pilot trial has provided the necessary data to design future randomized-controlled trials that can be implemented in the community in an ecological feasible manner.
